Lists the recommended browsing domains for a specific dns domain.
This can be used to find interesting domains for the domain
you are currently in. These can then be browsed with <a class="link" href="gnome-vfs-2.0-gnome-vfs-dns-sd.html#gnome-vfs-dns-sd-browse" title="gnome_vfs_dns_sd_browse ()"><code class="function">gnome_vfs_dns_sd_browse()</code></a>.

<p>
Returns a list of domain names that is useful to
browse for standard services. The list is generated
by contacting the dns server of the domain part the
hostname and asking for the list of browse domains.
Then extra domains from a gconf setting is added.
</p>
<p>
The "local" domain is not normally returned by this.
Care should be taken with local services so that its
obvious that they are local, and cannot be confused
with non-local services.
